Key differences between Fortran and Grain
| Characteristic | Fortran | Grain |
|---|---|---|
| Syntax | Uses a traditional, verbose, and rigid syntax designed for mathematical and scientific computation; case-insensitive and line-oriented. | Has a modern, concise, and functional syntax inspired by OCaml and Elm; uses significant whitespace and is case-sensitive. |
| Paradigm | Primarily procedural and imperative, with some support for object-oriented and parallel programming in newer standards. | Purely functional, emphasizing immutability and first-class functions. |
| Typing | Statically typed with explicit type declarations; type inference is limited. | Statically typed with strong type inference and a Hindley-Milner type system. |
| Performance | Highly optimized for numerical and scientific computing; often delivers near-native performance. | Runs on WebAssembly, offering good performance for web applications but generally not as fast as Fortran for numerical tasks. |
| Libraries and frameworks | Rich ecosystem for scientific, engineering, and numerical libraries; limited for general-purpose or web development. | Smaller ecosystem focused on WebAssembly and functional programming; fewer libraries, especially for scientific computing. |
| Community and support | Large, established community in scientific and engineering fields; extensive legacy code and long-term support. | Small, emerging community; active development but limited resources and support compared to Fortran. |
| Learning curve | Steep for modern features and legacy code; easier for those with a background in procedural programming. | Moderate to steep, especially for those new to functional programming concepts. |
